A bookcase with minimalist lines, made up of a brushed iron frame with a transparent or coloured finish as requested and solid wood shelves with knots, which cross over and protrude from the outer structure. The dominant feature of the bookcase is the unity of the outer border of the shelves, following the natural shape of the wood. Depending on the dimensions requested, the structure of the bookcase must be fixed to the wall and in some cases even fixed shelf by shelf.
